So the main motivation is to avoid "jumpy" rendering, correct?

In principle style sheet downloading is also asynchronous process.
And CSS can do many things that may cause "jumps". 
So if we will require image to have known dimensions up front 
then this means that CSS has to be loaded before any initial rendering.

I mean that <img width=... height=...> is only one piece of the puzzle.

I think that in most cases will be better if we could package
complex pages into zip envelopes and deliver them in the whole.
That would be real solution of "jumps".  And <img width=... height=...> 
is a palliative.
